His daughter, Lydia Joy, was born in November with heart defects that he’s chosen not to specify publicly. She’s needed multiple surgeries and will need another at the end of this month, which will cause Kimbrel to step away from spring training for some time.

Kimbrel fought back emotions when talking about Lydia Joy yesterday at JetBlue Park.
